Why does my AC turn on every 10 minutes?

Short-cycling happens when the cooling cycle becomes much shorter than the usual 10 minutes, causing the compressor to turn on and off more often than usual. This excessive stopping and starting adds wear on the compressor while robbing your home of its cooling comfort.

How often should your AC kick on?

Ideally, a properly operating air conditioner should cycle for roughly 15 to 20 minutes, two to three times per hour.

Why does my AC cycle on and off so much?

Low Refrigerant

Another common cause of short cycling is low levels of refrigerant. Like a clogged air filter, low refrigerant can produce excess stress on your AC system and make it work harder. And it also causes overheating, which could lead to the frequent turning on and off.

How do I stop my air conditioner from short cycling?

The only way to resolve this issue is to replace the oversized unit with one that better suits your home. The refrigerant is leaking and has become low.

At its shortest, a cooling cycle will last for 15 minutes. This is how much time the compressor and air handler need, at minimum, to distribute cooling around the house. When the compressor runs in shorter cycles, especially under 10 minutes, then it's short-cycling and needs attention.

How often should an air compressor cycle?
